Occasionally the block size obeys the relationship a < k < 2a. An extended incomplete block design consists of a single replicate of each treatment in each block along with an incomplete block design with k* = k - a. In the balanced case, the incomplete block design will have parameters k* = k - a, r* = r - h, and λ*. Write out the statistical analysis. In the extended incomplete block design, we have λ = 2r - b + λ*.
